Nick Vivarelli International Correspondent Sudanese director Mohamed Kordofani’s feature debut “Goodbye Julia,” a timely morality tale that takes place just before the 2011 secession of South Sudan and won the Un Certain Regard section’s Prix de Liberté (Freedom Prize) at Cannes, has scored a raft of sales following its launch. The first Sudanese film ever to screen in Cannes official selection, “Goodbye Julia” is the story of two women — one from the North, the other from the South — who are brought together by fate in a complex relationship that attempts to reconcile differences between northern and southern Sudanese communities in the currently war-ravaged country.
